Regulated non-quarantine pest Project

An EU funded project for the benefit of the whole EPPO region




NAME OF THE ORGANISM: Tobacco rattle virus (TRV000)


GENERAL INFORMATION ON THE PEST

Name as submitted in the project specification (if different to the preferred name):
 

Pest category:
 
Viruses and viroids


1- Identity of the pest/Level of taxonomic listing:

Is the organism clearly a single taxonomic entity and can it be adequately distinguished from other entities of the same rank?
 
Yes

Is the pest defined at the species level or lower?:
 
Yes

Can listing of the pest at a taxonomic level higher than species be supported by scientific reasons or can species be identified within the taxonomic rank which are the (main) pests of concern?
 
  • Not relevant: Seed potato sector, Ornamental sector
Is it justified that the pest is listed at a taxonomic rank below species level?
 
Not relevant

Conclusion:
 
  • Not evaluated: Seed potato sector, Ornamental sector
2 – Status in the EU:
 
Is this pest already a quarantine pest for the whole EU?
 

Presence in the EU:
 
Yes

List of countries (EPPO Global Database):
 
Austria (2004); Belgium (2004); Bulgaria (2004); Czech Republic (2004); Denmark (2004); Finland (2011); France (2004); Germany (2004); Greece (2004); Hungary (2004); Italy (2004); Latvia (2004); Lithuania (2004); Netherlands (2015); Poland (2014); Sweden (2014); United Kingdom (2004)

Conclusion:
 

Justification (if necessary):
 
Data of the presence of this pest on the EU territory are available in EPPO Global Database (https://gd.eppo.int/).

HOST PLANT N°1: Gladiolus (1GLAG) for the Ornamental sector.


CONCLUSION ON THE STATUS:
 
Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination was not identified by the experts of the ornamental SEWG as being a candidate for the RNQP status with specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the EU Marketing Directives for ornamentals.

HOST PLANT N°2: Lilium (1LILG) for the Ornamental sector.


CONCLUSION ON THE STATUS:
 
Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination was not identified by the experts of the ornamental SEWG as being a candidate for the RNQP status with specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the EU Marketing Directives for ornamentals.

HOST PLANT N°3: Narcissus (1NARG) for the Ornamental sector.


CONCLUSION ON THE STATUS:
 
Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination was not identified by the experts of the ornamental SEWG as being a candidate for the RNQP status with specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the EU Marketing Directives for ornamentals.


HOST PLANT N°4: Solanum tuberosum (SOLTU) for the Seed potato sector.


Origin of the listing:
 
PM 4/28 (1)

Plants for planting:
 
Plants intended for planting of nuclear stock, other than [true] seeds


3 - Is the pest already listed in a PM4 standard on the concerned host plant?
 
Yes
 
Conclusion:
 
Qualified

 
Justification (if necessary):
 
Experts agreed that the nuclear stock should be tested or derived from mother plants which have been tested for this virus.


CONCLUSION ON THE STATUS:
 
Recommended for listing as an RNQP, based on EPPO PM 4 Standard, only for the nuclear stock.


8 - Tolerance level:

Is there a need to change the Tolerance level:
 
Yes

Proposed Tolerance levels:
 
Zero tolerance, only for nuclear stock.

9 - Risk management measures:

Is there a need to change the Risk management measure:
 
Yes

Proposed Risk management measure:
 
Nuclear stock should be tested or derived from mother plants which have been tested for Tobacco rattle virus.
